Bloodhound experiments - balloon cars
Children from New Invention Junior School in the West Midlands investigate two ways that vehicles may be driven - energy directly applied to the axle and energy that is separate from the axle. The children make either wind up rubber band cars of balloon powered rocket cars. The children discover that the cars with two carefully placed balloons work much better than the others. But could the two balloons be arranged in a different way so that even more of the stored potential can be released? First broadcast on the Learning Zone on BBC in February 2012 for the series The Bloodhound Adventure.
Useful throughout an area of study looking at features of particular modes of transport. Discusses ways in which energy may be applied to vehicles in order to make them move. Science concepts: energy and potential energy; testing variables like number of balloons and axle length, fair testing and investigating are discussed. Can be used in conjunction with 13377
